DESCRIPTION

According to the principles of the present application, systems andmethods are described for a stowable check strap assembly for aremovable vehicle door system. The check strap assembly includes a checkstrap rotatably coupled to a bracket, allowing the check strap to belocated for easy attachment to a door detent. The bracket is in turnrotatably coupled to the vehicle body. When the vehicle door is removed,the bracket is rotated to move the check strap to a vertical positionwhere it can then be rotated toward the vehicle body to a low-profile,out of the way, and stowed position. Advantageously, no tools arerequired to remove or install the door, nor any additional steps todisengage the check strap assembly, such as actuating push buttons,levers, etc. Such a system rapidly speeds up the door removal andreattachment process.

With initial reference to FIG. 1 , a vehicle 10 is illustrated having abody 12 with a removable door system 14 in accordance with theprinciples of the present disclosure. The removable door system 14 atleast partially encloses and defines a passenger compartment 16 in whichthe vehicle driver and passengers sit during operation of the vehicle.In the example implementation, the removable door system 14 includesselectively removable doors 18 removably coupled to the vehicle body 12by one or more door hinge assemblies 20. As described herein in moredetail, each removable door 18 is operably associated with a stowablecheck strap assembly 22.

With reference now to FIGS. 1-4 , the removable doors 18 will bedescribed in more detail. In the example embodiment, vehicle 10 includesa pair of removable front doors and a pair of removable rear doors. Itwill be appreciated, however, that vehicle 10 can have any suitablenumber of doors, some or all of which include the stowable check strapassembly 22. For ease of discussion, only the front passenger side doorwill be described in detail, but it will be appreciated that any or allof removable doors 18 can be structurally and functionally identical orsubstantially similar thereto.

As shown in FIGS. 1-4 , removable door 18 generally includes an exteriorpanel 30 (e.g., sheet metal), an interior panel 32, and a perimeter sidewall 34 all at least partially defining an interior cavity 36 (e.g., seeFIG. 3 ). The exterior panel 30 includes a portion of the hinge assembly20, and the interior panel 32 is configured to receive one or morepieces of interior trim (not shown). Additionally, removable door 18includes a soft check strap 38 (e.g., nylon strap) having a first end 40and an opposite second end 42. The soft check strap 38 is configured tolimit maximum rotation of the door 18 relative to the vehicle body 12when rotatably coupled thereto. The first end 40 is coupled to theinterior panel 32 via a fastener 44, and the second end 42 is looped forremovably coupling to a footmans loop or hook 46 of the vehicle body 12to thereby limit maximum door rotation (e.g., 90°).

In the example embodiment, the side wall 34 defines a check strapaperture 50 configured to receive one or more portions of the stowablecheck strap assembly 22 therethrough, as described herein in moredetail. A door detent 52 is configured to couple to an inner side of theside wall 34 via one or more fasteners 54. In this way, the door detent52 is disposed within the door interior cavity 36 over the check strapaperture 50. The stowable check strap assembly 22 is operably andremovably coupled with the door detent 52 to provide one or more checksor detents to retain the door 18 in one or more predefined openpositions relative to the vehicle body 12. In general operation, thedoor 18 remains stationary in each detent position until a user appliesforce sufficient to move the door 18 away from the detent position.Advantageously, in the example implementation, the stowable check strapassembly 22 is removably coupled to the door detent 52 to enable theuser to remove the door 18 from the vehicle body 12.

With continued reference to FIGS. 1 and 2 , the door hinge assemblies 20will be described in more detail. In the example embodiment, the doorhinge assemblies 20 enable the removable doors 18 to pivot between aclosed position and an open position to allow a user of the vehicle 10to enter and exit the passenger compartment 16. Further, the door hingeassemblies 20 are configured to enable a user to quickly and easilyremove the door 18 from the body 12 of the vehicle 10 without any tools,or in alternative examples, using only simple tools such as a wrench,screwdriver, hex key, or other tool that may be conveniently storedwithin the vehicle 10. In this way, the user may quickly and easilyremove the entire door 18 from the body of the vehicle 10.

As shown in FIG. 2 , in the example implementation, each hinge assembly20 is comprised of a leaf 60 having a first knuckle 62, a second knuckle64, and a door pin 66. The leaf 60 includes a plurality of apertures 68configured to receive fasteners 70 for coupling the leaf 60 to thevehicle body 12. Alternatively, leaf 60 may be attached to body 12 byany suitable means such as, for example, via welding. The first knuckle62 is coupled to or integrally formed with the leaf 60 and is a tubular,substantially cylindrical member defining a receiving aperture 72extending therethrough.

The second knuckle 64 is coupled to or integrally formed with theremovable door 18 and is also a substantially cylindrical member. Thedoor pin 66 is coupled to a lower end of the second knuckle 64 andextends downwardly therefrom. As shown in FIG. 1 , the first and secondknuckles 62, 64 are configured to be aligned such that the door pin 66can be inserted through receiving aperture 72. In some examples, aretaining member (e.g., a nut, not shown) may then be coupled to abottom end of the door pin 66 to hingedly secure the door 18 to thevehicle body 12.

Turning now to FIGS. 5 and 6 , the stowable check strap assembly 22 willbe described in more detail. In the example embodiment, the stowablecheck strap assembly 22 generally includes a bracket 76, a check strap78, a stop pin 80, and a retaining clip 82. As described herein in moredetail, the stowable check strap assembly 22 is movable between adeployed position (FIG. 5 ) and a stowed position (FIG. 6 ). Thisenables the check strap assembly 22 to be positioned for coupling withthe door 18 when desired, and subsequently moved out of the way to thestowed position when the door 18 is removed from the vehicle body 12. Inthis way, the check strap assembly 22 can simply be moved to a stowedposition and does not require removal from the body 12, thereby speedingup the door removal process.

In the illustrated example, bracket 76 generally includes a base member84 with a fastener flange 86 and a pair of laterally spaced apart strapflanges 88 extending therefrom. The fastener flange 86 defines afastener aperture 90 configured to receive a fastener 92 (e.g., a bolt)for rotatably coupling the bracket 76 to the fastener 92 and/or vehiclebody 12. This enables the bracket 76 to be rotated between a cross-caror transverse position (FIG. 5 ) and a vertical position (FIG. 6 ), asdescribed herein in more detail. The strap flanges 88 each include a pinaperture 94 configured to receive a pin 96 therethrough for rotatablycoupling the check strap 78 to the bracket 76.

In the example embodiment, the check strap 78 generally includes aproximal end 98 and an opposite distal end 100. The proximal endincludes a coupling base 102 with an arm or shaft 104 extendingoutwardly therefrom. The coupling base 102 is generally cylindrical anddefines a receiving aperture 106 to receive the pin 96 to secure thecheck strap proximal end 98 between the strap flanges 88. The shaft 104defines a first detent 108 configured to hold the door 18 stationary ina first predefined position when in the closed or substantially closedposition. The distal end 100 includes a detent body 110 coupled to theshaft 104. As shown in FIG. 5 , detent body 110 defines a second detent112 and a third detent 114. The second detent 112 is configured to holdthe door 18 in a second predefined position such as, for example, a 30°rotation relative to the side of the vehicle 10. Similarly, the thirddetent 114 is configured to hold the door 18 in a third predefinedposition such as, for example, a 45° rotation relative to the side ofthe vehicle 10. It will be appreciated, however, that check strap 78 mayhave any suitable number of detents for holding door 18 in variousdesired rotational positions.

As described above, in the example embodiment, check strap assembly 22includes stop pin 80 and retaining clip 82. Stop pin 80 is coupled toand projects outwardly from vehicle body 12. As shown in FIG. 5 , stoppin 80 provides a positive stop to engage bracket 76 and prevent furtherrotation thereof. In this orientation, the bracket 76 is located in thetransverse deployed position such that check strap 78 extends outwardlyfrom the vehicle body 12 and is disposed for coupling with the doordetent 52. Moreover, a biasing mechanism 116 (e.g., a spring) isoperably coupled about pin 96 between the bracket 76 and check strap 78.The biasing mechanism 116 is configured to bias the check strap 78 intoa predetermined install position, which when the door 18 is beingreattached to the vehicle body 12, allows the door 18 to be rotatedtoward the closed position and automatically re-engage the check strap78 and the door detent 52. As such, biasing check strap 78 to thepredetermined install position facilitates speeding up the doorinstallation process.

When door 18 is removed and the check strap assembly 22 is no longerneeded, the check strap 78 is biased to the install position, as notedabove. However, with the door 18 removed, the check strap 78 may be inan undesirable position that could hinder the ingress/egress ofpassengers or make the check strap assembly 22 more likely to bedamaged. Accordingly, to stow the check strap assembly 22 out of theway, the bracket 76 is rotated a predetermined distance (e.g., 90°counterclockwise as shown in FIG. 5 ) into the vertical stowed position.As shown in FIG. 6 , the check strap 78 can then be rotated toward thevehicle body 12 against the biasing force of biasing mechanism 116 andsubsequently secured in the position by the retaining clip 82.

In one example removal/installation operation, the removable door 18begins in the closed position, rotatably coupled to the vehicle body 12by the hinge assemblies 20. The check strap assembly 22 is operablycoupled to the door detent 52, and the soft check strap 38 is secured tothe hook 46. Beginning with the removal operation, the door 18 is openedand moves through the first detent 108, second detent 112, and thirddetent 114. The soft check strap 38 is uncoupled from the hook 46 beforethe door 18 reaches the maximum allowable rotation allowed by the softcheck strap 38 (e.g., 90° relative to the side of the vehicle). As shownin FIG. 4 , this enables the door 18 to continue rotating until thecheck strap 78 disengages the door detent 52 and is withdrawn from thecheck strap aperture 50, for example, at a 100° rotation relative to theside of the vehicle.

Once uncoupled from the check strap assembly 22, the door 18 can belifted such that hinge assembly door pins 66 are withdrawn out of thefirst knuckle receiving apertures 72, thereby disconnecting the door 18from the vehicle body 12. The removable door 18 may then be moved tostorage. With the door 18 removed, the check strap assembly 22 remainsin the deployed position (FIG. 5 ) with the bracket 76 oriented in thetransverse position and the check strap 78 biased to the installposition by the biasing mechanism 116. The check strap assembly 22 issubsequently moved to the stowed position by rotating the bracket 76counterclockwise (as shown in FIG. 5 ) to the vertical position (FIG. 6) and forcing the check strap 78 toward the retaining clip 82 to beretained thereby in the stowed position. Thus, the door 18 is quicklyand easily removed and the check strap assembly 22 stowed withoutrequiring any tools.

To perform the installation operation of door 18, the bracket 76 isrotated clockwise (as shown in FIG. 6 ) to the transverse position whereit is prevented from further rotation by the stop pin 80. This movementuncouples the check strap 78 from the retaining clip 82, and the biasingmechanism 116 biases the check strap 78 to the install position shown inFIG. 5 . The door 18 is then positioned relative to the vehicle body 12in an orientation greater than the check strap disengagement angle ‘α’(e.g., greater than 100°), for example, as shown in FIGS. 1 and 4 . Thehinge assembly door pins 66 are then aligned with the first knucklereceiving apertures 72 and subsequently inserted into the first knuckles62 to attach the hinge assemblies 20. The door 18 is then rotated towardthe closed position.

As noted above, the stop pin 80 and the biasing mechanism 116 positionthe check strap assembly 22 for automatic re-engagement between thecheck strap assembly 22 and the door detent 52. As the door 18 isrotated to the closed position, the check strap 78 is aligned forautomatic insertion through the check strap aperture 50 and into thedoor detent 52. Once the check strap 78 is re-engaged with the doordetent 52, the door 18 is rotated to a further predetermined position(e.g., 50° relative to the side of the vehicle) and the soft check strap38 is reattached to the hook 46, thereby quickly and easily completingthe reinstall without any tools.

Described herein are systems and methods for a removable vehicle doorsystem that requires little or no tools to remove the vehicle doors. Thesystems include a check strap assembly that is automatically detachedfrom a door detent when the door is rotated to a predetermined angle,thereby allowing the door to be lifted out of hinge assemblies andremoved from the vehicle. The check strap assembly is then rotated intoa stowed position and secured out of the way. When reinstallation of thedoors is desired, the check strap assembly is rotated to the deployedposition, the door is reattached to the hinge assemblies, and thenrotated to the closed position. During the close, the check strapassembly is automatically positioned and guided for re-engagement withthe door detent. As such, the system enables rapid removal andinstallation of vehicle doors without the need for tools.
